LONDON - Steven Gerrard wants Manchester City to help Liverpool's bid to snatch the Premier League title by beating Manchester United at Old Trafford on Sunday. Gerrard scored twice in a 3-0 victory at West Ham United on Saturday which took Liverpool back to the top of the table on goal difference, at least until second-placed United play City. "United have got a tough game," the England midfielder told Setanta Sports. "City have just come into a bit of form and derby matches are never easy so we wait and hope City can do us a favour." Liverpool and United have 80 points, with the Anfield team possessing a goal difference of plus-46 against the Old Trafford club's plus-40. However, Liverpool only have two matches remaining and United have four. Gerrard, with a personal-best 23 goals this season, said: "Our aim is to win our remaining games. CLEAN SHEET "We are happy with the result today and happy with the clean sheet and that puts more pressure on United. "If they go and win their games, fair play to them they deserve it. But we have to keep the pressure on." Gerrard put Liverpool ahead early and made it 2-0 after 38 minutes, forcing the rebound over the line after Robert Green saved his penalty. "I don't like blaming other people for my errors but (team mate) Jamie Carragher said to me this morning 'you are due a penalty miss aren't you?'. "He's getting the blame, he jinxed me," joked Gerrard. Ryan Babel also struck as Liverpool chalked up their ninth win in 10 league games. United, though, are well placed to land a third successive title and equal Liverpool's all-time record of 18 championships.
